***** case still pending!

I phoned in with a ***** case about a month ago, stating that our internet is being used by someone / something either than the office. They said that they would get back to me in 24 - 48 hours with information. I phoned them 2 days after I laid the complaint and they then told me that I would need to wait an extra 3 days since the case has now been transferred to their \investigations"team. I phoned them numerous times after I waited 3 days and they all tell me the exact same thing it is like they read it from a paper.. \""Mam"
